Check out the Tiobe Index (http://www.tiobe.com...tpci/index.html). It provides a list monthly of the most used programming languages0. The list is not specific to any industry, but you can at least gauge what kind of languages employers are looking for (to include the game industry).
Both schools are somewhat expensive (~$500 per credit hour), but financial aid is always available. I go to UMUC and its a decent program. There are courses offered in game development and computer graphics. Also, UMUC offers a lot of minors that can be earned completely online. I just finished the coursework for a minor in mathematics and only have four courses left in my major. If you want more information about UMUC specifically, let me know and I'll try to help you out.
